I wasn't raised by harsh beating, just the spanking and i believe i turned out all right. i do believe that as a young kid, like 2,3-6, it should be a little lighter physical disipline and when they have the judgement to realise that belts hurt thats when you threaten them with the heavier beatings. THREATEN them. obviously if they don't listen to you then go at it. I want my kids to love me and respect me, but not fear me and hate me for hurting them.
but that's just me.
